How to enable Ehcache 3.x JSR-107 MBean operations?

Why the following ehcache.xml doesn't allow to clear caches via JMX (the Operations tab is disabled in JVisualVM for MBean for cache management and enabled for cache statistic)? I use spring boot framework and specify ehcache.xml file location via spring.cache.jcache.config property and just use @Cachable spring framework annotation.

<config
    xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
    xmlns='http://www.ehcache.org/v3'
    xmlns:jsr107='http://www.ehcache.org/v3/jsr107'
    xsi:schemaLocation="
        http://www.ehcache.org/v3 http://www.ehcache.org/schema/ehcache-core-3.0.xsd
        http://www.ehcache.org/v3/jsr107 http://www.ehcache.org/schema/ehcache-107-ext-3.0.xsd">


  <service>
    <jsr107:defaults enable-management="true" enable-statistics="true"/> 
  </service>

  <cache alias="stringCache"> 
    <key-type>java.lang.String</key-type>
    <value-type>java.lang.String</value-type>
    <heap unit="entries">2000</heap>
  </cache>

</config>

Clearing cache entries is not supported by the JSR-107 specification. Only clearing the statistics is possible. To workaround that, you will have to create your own MBean.
